DIY Lawn Mower Motor Repair

A lawn mower is a primary piece of equipment in the care and maintenance of any home with a lawn. Help to keep your lawn mower running well by performing easy do-it-yourself lawn mower motor repair. The money saved will be well worth it.

Tips Before Getting Started



  • Wear eye protection.

  • Wear gloves when possible.

  • Disconnect the spark plug to ensure that the mower does not start while you are working on it.

  • Wait until the motor is cool before attempting to work on it.

  • Follow all of the manufacturer’s recommendations.

  • Easy Lawn Mower Repair Areas



  1. Change the oil. Changing the oil on your lawn mower is easier than changing the oil in your car. New, clean oil helps the motor to work at the most efficient level. Follow the manufacturer’s recommendations for the correct oil mixtures. Changing the oil at the recommended intervals will extend the life of your mower.

  2. Clean or change the air filter. Because there is so much dust and dirt kicked up when you use your lawn mower, the air filter will need to be replaced often. A clogged air filter will eventually cause the motor to die because sufficient air is not getting to the engine.

  3. Change the spark plugs. Be sure to use the correct spark plugs for your mower. Also, remember to use a feeler gauge to gap your spark plugs to the correct size for your mower. A worn-out spark plug will make your lawn mower hard to start.

  4. Replace the fuel filter. A blocked fuel filter will cause the mower’s engine to shut off because enough gas is not reaching the engine.


Not all lawn mower repairs can be handled by the average homeowner, but those that can be performed by anyone will save you a lot of money versus having your lawn mower serviced professionally.  You mow your own lawn to save a buck; why not perform the basic do-it-yourself repairs to your lawn mower motor and save some more?
